Plush Firm Mattresses with Cooling Materials
Firm mattresses give you the most support of our everyday comfort levels — a solid, stable surface that keeps your spine aligned instead of sinking in. Firm is the go-to for back and stomach sleepers, heavier-weight sleepers who need extra support, and anyone looking for orthopedic, back-friendly comfort; side sleepers or those who like a softer feel may prefer our medium or plush options. Choose from tight-top, foam, euro-top and hybrid builds across Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Chirofoam and our own NM line — from budget-friendly models at $59 to premium, with free delivery across Canada. • Feel: firm gives a solid, supportive surface with minimal sink-in • Best for: back and stomach sleepers, heavier-weight sleepers, and orthopedic / back-pain support • Consider softer if you sleep on your side or want more cushioning — see our medium or plush options • Constructions: tight-top (most firm beds), foam, euro-top and hybrid • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Chirofoam, Springwall & NM • Prices: from $59 (budget) to premium — our widest price range • Want the firmest feel?

How Cooling Materials Work in Modern Mattresses
A mattress’s cooling performance depends on its overall construction. Gel infusion can delay the initial warming of foam by increasing thermal mass; it does not provide a continuing path for heat to leave the bed. Natural latex has an open-cell structure that promotes continuous airflow without any added chemicals, and hybrid mattresses with individually wrapped coils create air channels beneath the comfort layers that vent heat away from the sleep surface.
When choosing a cooling mattress, match the technology to your sleep style. Hot sleepers who prefer a conforming feel can compare memory foam models from Serta, Serta iComfort, or Tempur-Pedic, paying attention to airflow and cover construction. If you want natural breathability without synthetic foams, Natura and Sealy Posturepedic Natural Origins offer latex-based options. Budget-conscious shoppers can find cooling gel foam mattresses from Springwall and NM. All cooling mattresses at National Mattress are manufactured in Canadian factories 🍁 and ship with free express delivery across Canada.
Gel-Infused Foam
Thermal-conductive gel beads absorb and dissipate body heat. Found in many models from Serta, Sealy, Beautyrest, and Springwall.
Coil Airflow Systems
Individually wrapped pocket coils in innerspring and hybrid mattresses create air channels that continuously vent heat from the core.
Graphite & Copper Infusions
Compare the complete construction of Serta iComfort and Beautyrest models. An infusion name alone does not establish sustained cooling performance.
Cooling Cover Fabrics
Phase-change and moisture-wicking cover materials feel cool to the touch and regulate surface temperature throughout the night.
